Answer:
[Fe(NO₃)₃] = 0.90 M
Explanation:
Molarity = Mol/L
Total volume of solution: 31.65 mL + 44.96 mL = 76.61 mL
Let's determine the moles of salt ([M] . volume)
0.03165 L . 1.07M = 0.0338 moles
0.04496L . 0.79M = 0.0355 moles
Total moles Fe(NO₃)₃ = 0.0338 + 0.0355 = 0.0693 moles
Volume of solution = 76.61 mL = 0.07661 L
0.0693 mol / 0.07661 L = 0.90 mol/L
Answer:
5 km North
Explanation:
Displacement refers to the distance covered in a specific direction.
In this case,
Distance covered due north = 8 km
Distance covered due south = 3 km
Therefore;
If we take the distance towards north to be +8 km
The distance towards south to be - 3 km
Then;
Displacement = +8km + (-3km)
= + 5km
= 5 km North
Therefore;
The displacement is 5km towards North.
Answer:
restrict population growth ( second choice).
Answer:
The cation is written first in the name; the anion is written second in the name. Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written in parentheses with the subscript written outside the parentheses.
Yes, it is the power of material evidence that wins.
- Evidence used to support or refute a scientific theory or hypothesis is known as material evidence.
- Evidence is also used by scientists in various contexts, such as when they apply ideas to real-world issues.
- Whether a person accepts the data as proof depends on their presumptions or views regarding how observations relate to a theory.
- A creative hypothesis is developed by a scientist and may be refuted by testing it against evidence or established truths.
- Evidence can refute a hypothesis by demonstrating facts that are at odds with it. In contrast, the presence of evidence does not preclude the possibility of future, undiscovered evidence supporting the idea.
Therefore, it is the power of material evidence that wins, not the authority of experts that
proves an answer in Science.
